High Efficiency Graphene Coated Copper Based Thermocells Connected in Series

Emerging markets for wearable electronics have stimulated a rapidly growing demand for the commercialization of flexible and reliable energy storage and conversion units (including batteries, supercapacitors, and thermoelectrochemical cells). 3D printing, a rapidly growing suite of fabrication technologies, is extensively used in the above‐mentioned energy‐related areas owing to its relatively low cost, freedom of design, and controllable, reproducible prototyping capability. However, there remain challenges in processable ink formulation and accurate material/device design. By summarizing the recent progress in 3D‐printed wearable electrochemical energy devices and discussing the current limitations and future perspectives, this article is expected to serve as a reference for the scalable fabrication of advanced energy systems via 3D printing.

Samarium doped tin oxide (SmDTO) nano particles were synthesized and deposited in the form of thin film by RF sputtering and was characterized using XRD and SEM. XRD images revealed the crystalline nature of tin oxide and reduced peak intensities in doped samples. SEM micrographs showed fine granular nature of tin oxide, mostly spherical and well isolated grains and slight agglomerations in doped sample. The current – voltage behavior of samarium doped tin oxide thin film was investigated using Electrochemical Impedance Spectroscopy (EIS). Temperature dependent EIS was performed on 0.5% SmDTO thin films to analyze the effect of doping on its charge transfer resistance. Due to doping, the charge carrier concentration improved surface conduction in SnO2 thin films which was reflected as a steady and gradual decrease in the charge transfer resistance.
